Intel® Core™2 Quad Processor
New version now available based on Intel’s 45nm technology
Overview
The Intel® Core™2 Quad processor is the latest in cuttingedge
processor technology for the desktop PC. Based on
the new Intel® Core™ microarchitecture, the Intel Core 2 Quad
processor delivers four complete execution cores within a
single processor, delivering unprecedented performance and
responsiveness in multi-threaded and multi-tasking business
and home environments.
The unprecedented performance of the Intel Core 2 Quad
processor is made possible by each of the four complete
execution cores delivering the full power of Intel Core
microarchitecture. More instructions can be carried out per clock cycle, shorter and wider pipelines execute commands
more quickly, and improved bus lanes move data throughout
the system faster. This quad-core processor represents Intel’s
continued leadership and drive of multi-core processing and
more parallel computing.
The latest versions, built on Intel’s 45nm manufacturing
technology, take these benefits to a whole new level. This
new technology uses hafnium-infused Hi-k transistors,
enabling even more processor performance by doubling the
transistor density, improving efficiency and speed relative to
the previous generation, and increasing cache size by up to
50 percent. These new Intel Core 2 Quad processors deliver
even more performance without using more energy.
Doing More with Intel® Quad-Core
The Intel Core 2 Quad processor is at the center of today’s
most interactive and content-rich software experiences. The
evolving set of threaded multimedia applications, including
digital content creation, will shine as users are able to complete
tasks faster. Game play can achieve even greater visualization
and realism as tasks such as artificial intelligence (AI), physics,
and rendering can be distributed across each of the four
complete execution cores and run in parallel....
Features and Benefits of the Intel® Core™2 Quad Processor
Features Benefits :----
Quad-Core Processor Provides four complete execution cores in a single processor with up to 12 MB of L2 cache and up to a
1333 MHz Front Side Bus. Four dedicated, physical threads help operating systems and applications deliver
additional performance, so end users can experience better multi-tasking and multi-threaded performance
across many types of applications and work loads.
Intel® Wide Dynamic Improves execution speed and efficiency, delivering more instructions per clock cycle. Each of the four
Execution cores can complete up to four full instructions simultaneously.
Intel® Smart Memory Access Optimizes the use of the data bandwidth from the memory subsystem to accelerate out-of-order execution.
A newly designed prediction mechanism reduces the time in-flight instructions have to wait for data. New
pre-fetch algorithms move data from system memory into fast L2 cache in advance of execution. These
functions keep the pipeline full, improving instruction throughput and performance. 45nm versions further
improve this feature, with more efficient methods of loading and storing data in main memory.
Intel® Advanced Smart Provides shared level 2 cache across each pair of cores that can be dynamically allocated to each processor
Cache1 core, within the pair, based on workload. This efficient implementation increases the probability that each
core within the pair can access data from fast L2 cache, significantly reducing latency to frequently used
data and improving performance.
Intel® Advanced Digital Accelerates the execution of Streaming SIMD Extension (SSE) instructions to significantly improve the
Media Boost performance on a broad range of applications, including video, audio, and image processing, and multimedia,
encryption, financial, engineering, and scientific applications. The 128-bit SSE instructions are now issued
at a throughput rate of one per clock cycle effectively doubling their speed of execution on a per clock
basis over previous generation processors. 45nm versions include a new Super Shuffle Engine, which
improves existing SSE instructions while enabling significant gains on the latest SSE4 instruction set.
SSE4-optimized applications, such as video editing and encoding in high-definition resolution, will see
additional performance improvements.
Intel® Virtualization Allows one hardware platform to function as multiple “virtual” platforms. Intel® VT improves manageability,
Technology (Intel® VT)2 limiting downtime and maintaining worker productivity by isolating computing activities into separate partitions.
Intel® 643 Architecture Allows the processor to access larger amounts of memory. With appropriate 64-bit hardware and software,
platforms based on an Intel processor supporting Intel® 64 architecture can allow the use of extended
virtual and physical memory.
Execute Disable Bit4 Provides extended virus defense when deployed with a supported operating system. Memory can be marked
as executable or non-executable, allowing the processor to raise an error to the operating system if malicious
code attempts to run in non-executable memory. This can prevent the code from infecting the system.
Digital Thermal Sensor (DTS) Provides for more efficient processor and platform thermal control improving system acoustics. The DTS
continuously measures the temperature at each processing core. The ability to continuously measure and
detect variations in processor temperature enables system fans to spin only as fast as needed to cool the
system. The combination of these technologies can result in significantly lower noise emissions from the PC.
Intel Designed Thermal Includes a 4-pin connector for fan speed control to help minimize the acoustic noise levels generated from
Solution for Boxed running the fan at higher speeds for thermal performance5. Fan speed control technology is based on actual
Processors CPU temperature and power usage...
